Abstract

PCT No. PCT/SU80/00024 Sec. 371 Date Dec. 18, 1980 Sec. 102(e) Date Dec. 18, 1980 PCT Filed Feb. 13, 1980 PCT Pub. No. WO80/02320 PCT Pub. Date Oct. 30, 1980.A method for flame spraying of gunite on the lining of metallurgical units, comprising a delivery of a mixture of a refractory material and fuel in a central axisymmetric flow and a delivery of oxygen in an annular flow concentric with the flow of the refractory material and fuel, a heating and fusion of the refractory material in a high-temperature flame, and applying particles of the refractory material to the surface of the lining. Oxygen is delivered in a tapering annular flow rotating about its axis. The ratio between the rotation momentum of the oxygen flow and the momentum of the flow of the refractory and fuel is maintained in the range of 0.3 to 3.0.
